I have not heard of LCPM audio do you mean PCM? If so I think PCM audio is the most compatible.

PCM and Dolby Digital.

I don't know how compatible MPEG is in the audio realm, but I don't think ANY commercial DVDs use it. The nice thing about PCM is that it sounds fantastic and any hardware can decode it. Not all hardware can decode DD. Unfortunately, though, you cannot do PCM more than 2 channel on DVD Video.

For a master, i would suggest 6 seperate streams in raw pcm 48khz
theres no point in going higher as it will only be compressed again.

let the studio work out the compresion bitrate as well as the Dolby Digital config.

I know when i get projects, i prefer it to be as raw as possible. I no longer accept DAT tape due to phasing nuances with the mechanics of the different HW available.

DD may not be available on all machines, but any machines produced post 1999 are.

DD also cuts on storage requirements and DD regulation allows it to drop down to 384kbps as oppposed to 448kbps which is standard.

Peter,

I was refering to DVD. It is not a studio project. It is 400 DVDs that will be duplicated (not replicated) for a corporate client. I always use LPCM but wondered about the compatibility of the MPEG audio option on my software as it would save on file size. I stayed with LPCM.

Thanks for the replys.

Steve

Is it PAL or NTSC? As far as I know, NTSC DVDs does not support mp2 (mpeg audio). Just LPCM and the ac3 (the dolby thing...).
I'm authoring PAL DVDs, all with mp2 sound amd I didn't have any problem. LPCM takes to much space. It is used mostly for concerts, where sound is more important than video!
